Physical State; Appearance:
COLOURLESS
25-50% SODIUM SILICATE SOLUTION IN WATER
Physical Dangers:
Chemical Dangers:
The solution in water is a medium strong base.
Reacts
with
aluminium
and
zinc
forming flammable/explosive gas (hydrogen - see ICSC0001)
.
Occupational Exposure Limits:
TLV not established.
MAK not established.
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation
and
by ingestion.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.

The aerosol
is irritating to
the eyes
,
the skin
and
the respiratory tract
.
Effects of Long-Term or Repeated Exposure:
